Only One bug stopping IETester from being an awesome developer tool

I would love to use IETester on a regular basis but it fails 1 major piece of functionality I really need.

I need to be able to test popup window behavior but there are 2 things that stop it from working.

a.) The popup doesn't open as a popup, but rather as another tab. Although that is a "potential" behavior in IE7/IE8, if I requested a size for the popup I would like to have it appear as an actual popup on top of the main window. E.g. if I open a small calendar or chooser list popup it will look strange full-screen.b.) More importantly - I find that the new window doesn't pass the session token/headers or something as I *always* need to re-login

Other than this issue with popups, IETester appears to be a spectacular testing tool - however this issue is a significant roadblock.
